CONTROLLING MEANS FOR ELECTRIC CIRCUITS.

Application filed April a, 1906. Serial no; 809,616.

To all whom it may concern:-

Be it known that I, JULIUS K.

St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Circuit-Controlling Means for Electric Circuits, of which the followingis a specifi- My invention relates means and particularly to the contact makin and breaking portions thereof.

n the accompanying drawings-Figure 1, is an elevation of a portion of the said means, which is designed to be moved in either direction to come into and out of e gagement with a 006 erative portion. Fig. 2, is a plan view of t e parts shown in Fig.

in section on the line 33 of Fig. 2. Fig. 4, is a view partly in section on the lines 44' of Fig. 2; and showing a contact plate engagement with the spring contacts. Flg. 5, is a view of the cooperative contact piece. Fig. 6, is a view of 'the part shown n Fig. 5, taken-on line 66, F1 7, mounted on a post and showing the plia surfacesand the said- 0st and the pliable means for connecting t c said contact iece in circuit" independently of or conjomtly with the said post circuit or connection and showing a portion of a "suitable supportbarrier broken away and anarc restricting h erewit restricting barriers disposed at both sides of the contact piece,

the said barriers bein broken away at one end. Fig. 8 is a detal perspective view of a portion of the movable contact.

Referring to the drawin in detail; H indicates the insulation portions of the movable member, rotate together and are preferably made integral with the arc restricting barriers H H,

which are hereinafter described. 'The said movable member is adapted to all classes of is especially uited to making and breaking heavier circui #in one moveb step changes rent used, may

which are rigidly connected to ment than in the.reverse movement; as in heater clrcults; motor circuits; and others wherein step G, G indicate the movable contacts which are designed to engage a plurality of cooperating contacts. The sald contacts G, G are bifurcated but obviously they may be made of any suitable form or number of surfaces. The insulation ortion H forms a barrier about the movab e'contact G, exposing'the extremities of the latter in' roximity tothe fixed conductive parts hereinafter described. 7

H H? indicate barriers of insulation movable relatively to the insulation part H. The said barriers H are yieldingly-se'cured to the movable member by means of the yielding ends of movable contact G, and also by the springs G G The spring G bearing u on the sprin contacts G 'supplement t e contact ma g, stress .of the said contacts G, with the contact making stress of the springs G The said contact pieces C also separate the said barriers H, when the cooperative contacts are engaged sozhat in opening the circuit between the sa1 ed to pass the contact C riers. In closing the movable barriers H which they are in between the said barcircuit by way of the the power expended to siparate the said barriers relieves the mova e contact from a portion of its stress so that they are-more easily cooperatively enaged and when in engagement the parts %I G ress the cooperative contacts to-. gether. will be obvious that the said barriers H, H may extend to both sides circumferentiall of the movable contact. G. And it will likewise be'noted that the upper and lower barriers -H, .H need not uite touch to fulfil their are interrupting ctions. The said barriers H have shallow grooves formed in those faces thereof which piece 0, so as to dirub a ainst the contact vide reduce friction. on

', -I are yielding rubbing'contact surfaces movable barriers butlittle power is needelectrical contact between connected with the contact G, G. I is a non-yielding rubbing contact surface of electric conducting material extending entirely around the insulation member H and connected with the contact G, G. N, is a pliable conductor connected with the contact G, G. The said rubbing surfaces I and I and the pliable conductor N are adapted to permanently connect the contacts G and G with the service or apparatus that is to receive current as will be herein described.

C, is a contact adapted to be engaged (in either rotatable direction) by the movable contacts G. The contact C is slotted and loosely held on a reduced portion of the post 0 between'suitable shoulders with sufcient clearance to allow it to freely tilt a limited distance transversely and lengthwise. The said loose or floating connection or bearing between the portion C and the fixed part C allows the portion G to move into more perfect alinement and contact when the cooperative contacts are engaged.

C indicates a pliable conductor adapted to connect the contact part G to an electric circuit. The said pliable connection provides perfect electrical connection between the loosely borne part C and the circuit which may be connected the said part C free to find its best seat, or bearing, or contact, between the bifurcated ends of the contact G.

2 indicates a portion of the conductor C which is extended to the binding post C and secured thereto; thus making perfect the parts C and the part C free to move as The channel C in Fig. 6,

C comprises a binding post with binding screw of the usual form, said bindingpost being mounted upon a suitable support -A- having integral arc restricting barriers -A -A therewith, leaving named contact, an

I claim:

1. Circuit controlling means comprising cooperative contact members, one of which is movable about an axis into and out of sliding contact with the other contact member, and barriers of insulating material moving with'the movable contact member and located at opposite ends thereof, the barrier at one end being composed of parts springpressed toward each other and having their meeting faces in the plane of contact of the contact members.

2. Circuit controlling means comprising opposite contacts spring-pressed toward each other and movable about an axis, a cooperative contact having a portion thereof loosely supported in the path of movement of the meeting faces of the movable contacts and adapted to oscillate longitudinally and transversely.

3. In a controlling means for electric circuits, a fixed support, a contact loosely mounted upon the support to rock transversely and longitudinally, a flexible conductor between the contact and its support, a rotary element and contact members on said element and engaging opposite faces of the first named contact.

4. In a controlling means for electric circuits, a fixed support, a contact loosely mounted upon the support to rock transversely an longitudmally, a rotary element and contact members on said element osite faces of the first separable insulating barriers mounted upon the rotary element 1n juxtaposition to said contact members.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
